All Cat wants out of her life is her dream job, her dream man, and her favorite coffee. She could settle for one out of three, right?

Self-diagnosed coffee addict Cat Coleman believes her hard work as an unpaid intern for an entire year at a highly reputable interior design firm pays off when she excitedly accepts a full-time position with the company. However, instead of shadowing veteran designers, she's still sorting and delivering mail and making coffee runs. She simply went from unpaid intern to being the boss' personal assistant.

When a very grown-up and seriously sexy David Greenlaw from her Minnesota hometown begins an internship in the same business building, Cat tries to resist his boyish charms and flirty smiles. Because she knows his deceptively evil older sister, Gail, who made Cat's high school years a living nightmare, would happily pick up where she left off and tear down the new life she built.

Cat desperately wants to trust her heart and David's promises, but she distrusts Gail and her fake sweet smiles even more. When David's loyalty is tested, should Cat trust him to make the right decision or should she sacrifice her own happiness to ensure his?
